MADISON, Wis.--(BUSINESS WIRE)--Promega Corporation announces the introduction of a novel cytotoxicity assay that can be used on cell cultures for up to 72 hours, with flexibility for kinetic analysis to determine the onset of cytotoxicity. The CellTox™ Green Cytotoxicity Assay uses an asymmetric cyanine dye as a fluorescent marker that is impermeable to live cells but strongly binds DNA from dead cells, providing a signal that is directly proportional to cytotoxicity.
